Minecraft Got crashed spawned nearby a mobspawner

This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded MineCraft.

my minecraft is not moddod but i start it with magiclauncher..

Is Modded: Very likely; Jar signature invalidated

Your Minecraft is modded.

and even with oroginal launcher it crahes!!!!!!!!

magic launcher automatically deletes the META-INF folder, so it is actually modded. But this bug occurs in the original version of minecraft too indeed.
